Obviously, Yang Tong's flight learning was very successful, but in the following days, she still had to continue to familiarize herself with the Victory Feiyan every day, from performance to appearance, from flight to landing, from overhaul to combination, nothing could be left behind, this is the course specially arranged for her by Lina. Pen "Fun" Pavilion www.biquge.info

In addition, Horii decided to join as well, and although he was hit by Kudo, he would not give up. So, there is this scene today.

It was in the break room of the TPC ground combat base, and the break room was huge, almost the entire building, with a total of five floors. The first floor is an indoor basketball court, a swimming pool on the second floor, a billiards room on the third floor, a chess and card room on the fourth floor, and a game machine room on the fifth floor.

When Yang Tong is bored, he often goes to the game room to play games, and then is pulled out by Guangcheng with a look - penalty station!

And now, Yang Tong and Horii are standing in a room in the billiards room, there is only a billiard table, a table and two stools, there is still water on the table, and nothing else is there, very simple.

"This is what you're going to teach me?" Yang Tong frowned, looking at the billiard cue handed over by Horii, which was still American.

"Of course!" Horii nodded, holding the pole in front of her, motioning for her to take it. He hadn't forgotten what Kudo said that this guy didn't like to teach words, so he changed his approach, "I'll teach you some physics today." ”

Yang Tong took the pole, but his eyes narrowed, "Do you have to take the physics test to enter the victory team?"

"Of course I have to take the test," Horii lied without blushing and heartbeat, "I took the test when I went in, and it was not only physics, but also chemistry, biology, machinery, advanced mathematics, flight, astronomy, and manufacturing. ”

"Really?" Yang Tong didn't believe Horii's words, she had beaten him so many times, he didn't hold a grudge against her, and he was kind enough to teach her?

Thinking about it, he turned his head to look at Lina, who was sitting, and Lina nodded slightly. Seeing this, Yang Tong turned his head to look at Horijing: "Okay, I'll trust you once." However, Yang Tong didn't see it, and Lina in the corner couldn't help but laugh silently, but just for a moment, she returned to a faint appearance.

"Okay, let's start, I want the singular. ”

"Even numbers. ”

"Okay," Horii nodded, put the cue ball in its fixed position, and then, bent down, aimed the ball in his hand at the cue ball, and hit it with a snap, almost at the same time, there was another sound, and the triangular ball was instantly scattered, "I like to play because it reminds me of particle collisions in the accelerator, like the thrusters in the tail of the Victory Swallow." ”

The corners of Lina's mouth hooked, that guy from Horii has finally begun!

"Whoever scores the black ball first wins," Horii looked at the red ball that rolled towards the diagonal hole, "It's five, odd, mine." What a blessing. ”

"What is particle collision?" Yang Tong didn't look at the ball, but looked sideways at Horii and threw out his own questions.

Horii narrowed his eyes, and look, isn't the fish taking the bait?

"It's easy," Horii said around the edge on the left to the starting position, taking the club and aiming at the white ball, forming a three-point line against the yellow ball No. 3.

He snapped it out, then stood up and explained: "It refers to the process by which two particles interact with each other from far and near, thus changing the state of motion or transforming into other particles."

This process is also known as scattering, and it's like when you converted the energy of the Triumph Flyer into particles yesterday, and they convert into other particles, eventually forming a protective shield.

Still, I don't know how you did it, or how many trials have yielded results. It's your turn. ”

Horii said, watching Yang Tong frown and lower his body and start aiming at the cue ball and the purple No. 10, and continued: "When playing billiards, you must aim." There is also a physical force interaction, and there is also a change in angle. angles can also work together with force. ”

"Force and angle?" Yang Tong was stunned, and then, with a snap, he hit the No. 10 ball into the hole.

"Yes, it is often said in physics that the angle of exit of light is equal to the angle of incidence, but that is only in an ideal state. The action of the force on the object is multifaceted, and there are two forces in total: the motive force and the active force.

Fixed objects usually have gravity, centrifugal force, friction, and resistance, while moving objects are more troublesome, and it requires the selection of a reference.

For example, in the billiards we are playing now, the two of us each hit the billiards twice, and in the same space at different times, the results of all the impacts are the same, and at the same time, the mass of the ball does not change, of course, the mass is gravity.

Using the table as a reference, there is no change in the mass of the ball, no change in the velocity vector, and no change in the momentum exchange between the two balls.

Of our four hits, three went into the hole and one didn't. In other words, the force, kinetic energy, and potential energy of the ball have changed.

In this process, the force on the ball is friction, thrust, drag (friction) and gravity, according to Newton's three laws proposed by Isaac Newton in the United Kingdom, the force will always be conserved.

However, that is also in an ideal state, because in addition to the influence of force, the object is also affected by kinetic and potential energy, and the most important one, that is, ...... Retransmission of the medium. ”

"Relay of the medium?"

Smack-

There was a muffled sound, because of doubts, Yang Tong used less force, but he didn't get in.

"That's right," Horii said as he walked up to her, setting his cue club on the pool table and aiming for the cue ball and the number 9 ball, "On Earth, the medium of propagation is usually moving air, which we often call wind.

In the still air, the force on the ball is no different from what everyone thinks, except for the roughness of the table, which is the force.

But if it is in water, it is different, the speed of the ball and the force under it, including kinetic energy and potential energy, will change, if there is no force in the universe, the object will be stationary forever or endlessly moving. ”

Hitting the ball into the hole, Horii suddenly stood up, looked at Yang Tong, and said: "Do you think, is it to stop, or to move endlessly?"

Stop, or endless movement?

Lina was stunned, not only her, but also Yang Tong.

Horii's words are not just physical explanations, but also include the future of humanity and the future of monsters. Is it stopping, or is it an endless movement?

This is not the final result, because it is affected by various aspects, human greed, monster selfishness, although it cannot be generalized, but just like the forces that interact, humans and monsters, also interact.

Either they die, or they die on their own.

It is impossible to stop, and it is impossible to move endlessly.

Yang Tong shook his head, hit his ball in, was silent for a long time, and finally said, "This is a problem." ”

Lina and Horii were also lost in thought, knowing that Yang Tong had answered the final question: to live or to die, this is a question.

Yang Tong has a strong receptive ability, and during the teaching period of the two people, he absorbed and became proficient in the knowledge taught by the two to the greatest extent, even including the computer knowledge taught by Ye Ruilai.

As for Zongfang, Xincheng, Dagu, and Megumi in the middle, they haven't been here once because of their busy schedules, let alone teaching.

Munakata even went to teach Shirota Takao in person, from the most basic teaching to the flying attack, the combat method is the same.

A month passed quickly, and on the twentieth of October, something happened. A spaceship carrying friends and family approaches TPC's Delta space station in an attempt to attack the space station with an ion cannon. However, after the spaceship was destroyed by the Delta space station, it used this as an excuse to launch an invasion.

The spaceship was on board a family of three, and after the father of the Raculan escaped, he covered up the truth that he had abandoned him. On the grounds of the destruction of the spaceship and the revenge of the wife and daughter of the co-passengers, he approached Yanase Technical Officer.

At the same time, he killed the court technician, and wooed Yanase and his daughter Lina, intending to let Lina taste the 'pain of hell', but was stopped by the GUTS team members who came to the rescue, and after returning to his own planet, he became angry and fought fiercely with Tiga, and finally lost to Tiga.

In the process, Lina's long-cherished knot with her father is finally untied, and she keeps the lipstick that her father bought for her many years ago.

When the Lei Chulan star man appeared, Yang Tongren was still listening to the old woman's chatter at home. Ye Rui came to Asama's mother-in-law's house after work and told Yang Tong about it.

After listening, Yang Tong's eyes couldn't help but widen, "Good dog blood!"

"Although this is true, but in any case, it is best for Lina to reconcile with her father," Ye Rui looked at her with a smile, and then leaned closer to her, "You're going to compete with Takao Shirota in a few days, how do you feel?"

"It's not good, but I'm going to get in the winning team. ”

"Then I wish you success," Ye Rui took out the PSP in his pocket and handed it to her, "This is a gift, and we can play games online in the future." ”

Yang Tong looked at the game console in front of him and raised his eyebrows: "Are you so sure I can enter?"

"Of course, don't you think so?"

"Huh~" sneered, Yang Tong took the PSP and threw it in his hand, and then threw it back: "Let's talk about it when I win, I don't have a sense of accomplishment at all now." ”

"This ...... All right. I'll go first, and I'll go back tomorrow to write a post-war summary. Mother-in-law Asama, go first, thank you for your hospitality. Ye Rui nodded, stood up with the PSP, turned his head to say hello to Granny Asama and left.

"That kid, you're leaving so soon?" Granny Asama walked out and turned her head to look at the watermelon on the stone table, "I haven't eaten much." ”

"He doesn't eat it, I eat it myself. Yang Tong opened his mouth indifferently, picked up a piece of watermelon and was about to bite it, however, before he could start moving, a new white flip phone appeared in front of him.

Yang Tong was stunned and looked up at Granny Asama: "Old woman, what are you going to do?"

"Take it, the old woman saved up for a long time to buy it. Mother-in-law Asama sat down and put her mobile phone in front of her: "In the future, if you come back late, you have to make a phone call to come home, old woman, I know that you are very busy, and you often get off the night shift."

I heard Ye Rui say, you want to join the victory team, although I don't know what kind of job it is, but I think you may not come back for a long time, or even not come back, and I don't expect you to accompany my old woman every day.

Just hope you can give me a call and let me know how you're doing. ”

"Knowing the old woman, you are really verbose, as if you were saying your last words. Yang Tong put the mobile phone into his clothes, and he looked very impatient. It's just that she sniffed as she bit into the watermelon, and then didn't say anything.

Granny Asama smiled, removed the grapes from the fruit bowl and placed them in front of her, and said with a smile, "Then don't forget, this is what you promised the old woman." ”

After eating the watermelon, Yang Tong threw the grapes that Asama's mother-in-law had placed in front of her into her mouth, and said indistinctly, "You are so long-winded!"

"Hahahaha......" Mother-in-law Asama smiled very happily, raised her hand and patted Yang Tong's head, her eyes were full of love.

But it attracted Yang Tong's roar: "Old woman, don't touch my head!!"

The relationship between Yang Tong and Asama's mother-in-law has always been so simple, flowing as plainly as a stream.

October 30 will soon arrive, and the competition between Yang Tong and Takao Shirota will be on this day, at the TPC Far East Headquarters Base.

The chief examiner of this day included all the staff personnel in the upper echelons of the TPC, and the spectators were seven members of the victory team, after all, they were the combat personnel of the victory team, and there was no reason not to come.

The others are Mitsusei, Takizawa, and Ishino of the TPC Ground Combat Unit, and Yamamoto, Akaki, and Matsushita of the TPC Air Combat Unit.

Finally, Yang Tong and Shirata Guinan, the competition time is four o'clock in the afternoon, because not only to assess the combat ability during the day, but also to assess the combat ability at night, both of which are indispensable.

"Why does that kid look so small?" Seeing Yang Tong, Sawai couldn't help frowning, he didn't want the TPC to recruit minors, you know, Japan's juvenile protection law is very strict, even the TPC can't violate it.

"She's eighteen years old, Director Sawai. Guangcheng frowned, and said lightly: "Wasn't Yerui only sixteen when he entered the guts?"

As soon as Ye Rui was mentioned, Sakai stopped talking, and he approved Ye Rui's entry at the beginning, but the law on the protection of minors at that time was not perfect.

"Two, please enter the Victory Feiyan beside you. Megumi looked at the two of them, her voice was calm, but with the majesty of a captain, "After entering, check the performance of the fighter by yourself, and then request to take off after confirming that it is correct." ”

As he spoke, his eyes fell on Yang Tong's body, and his eyes gradually became darker, but he quickly retracted his gaze and spoke: "Do you understand?"

"Understood!" the two replied in unison, then turned around and entered the new Victory Feiyan.

Fastening his seat belt, Takao Shirata took a deep breath, turned his head, and glanced at Yang Tong, who was already wearing a helmet, through the glass, his eyes couldn't help but narrow, this time, he must win this position, no matter who the opponent is.
